加行高斯白噪声下的低密度奇偶校验码的算法，简单的程序，对初学者有用。(Add the line under the Gaussian white noise low-density parity-check codes of the algorithm, a simple procedure, useful for beginners.)

当信噪比较大时，采用广义最小二乘法可能会出现多个局部收敛点，解决这个问题的方法可用多级最小二乘法，一般来说多级最小二乘法包含三级辨识过程。利用输入输出数据，通过多级最小二乘法，可分别求的辅助模型，过程模型和噪声模型的参数估计值。在高噪声的情况下，多级最小二乘法明显优于广义最小二乘法，其收敛点唯一。(When the signal noise ratio (SNR), and by use of the generalized least squares method may appear more local convergence point, the way of solving this problem can be used multistage least squares method, and generally multistage least squares method includes three identification process. Using input/output data, through the multistage least squares, respectively for the auxiliary model, process model and noise model parameter estimation. In the high noise, multistage least squares method is obviously superior to the generalized least squares method, and its convergence point only.)

这个可以用来在元胞自己增加车流使用是好用的额(This can be used to increase traffic in cellular own use is the amount of usefuladd car)

LCMV算法的测试，能形成图形自己亲测，比较好的。 (Lms and RLS algorithm simulation, personally tested, can be used, very )

本函数主要用于计算两个参考数列与待测矩阵之间灰色关联度，返回值为综合关联度 综合关联度系数设默认为0.5(This function is mainly used to calculate the gray correlation between the number of columns and the two reference test matrix, the return value is the comprehensive correlation degree overall correlation coefficient of 0.5 set by default)

dw to xls 这个是用于pb9下的,已经修改过，不会弹出demo。 pb8的。 pb8设置有点麻烦，因为pb9是可以直接把(dw to xls)

运用tls-esprit方法估计信号简谐波频率(Estimation the frequencies ofsignal using total least square-esprit algorithm)

ofdm基带传输，信道编码，QPSK调制，卷积编码(the OFDM baseband transmission, channel encoding, QPSK modulation, convolutional encoder)

AM系统进行设计、仿真（仿真用程序实现），要求用程序画出调频信号波形，调频信号振幅谱，解调信号(AM system design, simulation (simulation applications to achieve), asked to use the program draw the FM signal waveform, the amplitude spectrum of FM signal, demodulate the signal)
